  • Control apparatus and control method for automatic transmission
    Patent number: 9915342
    Abstract: A control apparatus for an automatic transmission includes an ECU. The ECU stores a N?1 speed downshift/a N?2 speed downshift/a N?1 speed upshift/and a hysteresis lines. The hysteresis line is a predetermined distance above the N?1 speed upshift line, and is below the N?2 speed downshift line. The ECU controls the speed of the automatic transmission based on a quantity of state of a vehicle, and the plurality of stored shift lines, and execute, when an N speed is established, a first downshift that changes a speed from the N speed to an N?2 speed, when the quantity of state of the vehicle is in a region above the hysteresis line, after the quantity of state of the vehicle has risen above the N?1 speed downshift line.
